Is there any string function that can calculate how many characters in a data variable in irule?

Hello, For example I would like to know how many characters in [HTTP:uri] , is it possible to do so? Thanks

    Hello,

    I have given it a try but faced problem:

    when HTTP_REQUEST {

    set thisuri [HTTP::uri]

    ...

    }

     

    when HTTP_RESPONSE {

    if { [HTTP::status] == 404 } {


    if { [ string length $thisuri ] > 2 } {

    HTTP::respond 404 content "
    <html>
    <head>
    <title>Not Found</title>
    </head>
    <body>
    <h2>Not Found</h2>
    This page is not found.<br>
    <p></p>
    </body>
    </html>


    } else {

    HTTP::respond 404 content "
    <html>
    <head>
    <title>Not Found</title>
    </head>
    <body>
    <h2>Not Found</h2>
    This website is not found.<br>

    <p></p>
    </body>
    </html>
    "
    }
    }

     

    But I faced this error

    01070151:3: Rule [/Common/check_url] error: /Common/check_url:63: error: [parse error: missing "]["

    line 63 is  HTTP::respond 404 content "

    line 61 is  if { [string length $thisuri] > 2 } then {

    Any idea? Thanks
